Bryan Miller
Pastor Bryan Miller
Children’s Ministry Pastor
Pastor Miller was born in Canton, Ohio, but considers Chandler, Arizona to be his hometown. He distinctly remembers accepting the Lord as his Savior at age 6: “I was on top of my bunk bed, wearing Mickey Mouse pajamas. I had just spent a week at day camp. A message from camp held onto my heart, and I knew I needed to ask Jesus to be my Savior. So, right there in my bed I prayed and asked the Lord to save me from my sins.” This experience undoubtedly influenced Bryan’s later decision to work in children’s ministry. He received a B.A. in Pastoral Studies from International Baptist College and Seminary and became Children’s Pastor at Tri-City Baptist Church in 1996, though he had already been serving in their children’s ministry for ten years. Bryan and his wife Debbie have three children: Erin, Emily, and Andrew.

DJ Oldham
Pastor DJ Oldham
Re:Vive (college)
Pastor DJ was born in Asheboro, North Carolina. He began a personal relationship with Jesus Christ after accepting Him as His only means of forgiveness and righteousness at the age of 6 years old. In his Junior year of High School DJ surrendered his life to anything God had for him at the Wilds Christian Camp. After this turning point in his life, God led him to serve in various roles within the church directing children’s and youth ministries as well as two pastoral internships related to college ministry.
While initially pursuing a degree in civil engineering to help his father with their family business, DJ’s primary purpose of attending college changed to personal evangelism and outreach on the college campus. God allowed him to stay in that mission field for 13 years as he shared the gospel to fellow students from all over the world. DJ holds a PhD in Nano Engineering from North Carolina A&T and a PhD in Civil, Environmental, and Sustainable Engineering from Arizona State University. DJ taught as an adjunct professor at Bob Jones University for one semester until he knew God was calling him next to college ministry at Tri-City Baptist Church. DJ is currently serving as the Men’s Dormitory Supervisor of International Baptist College and Seminary and the College Pastor of Tri-City Baptist Church. DJ and his wife Angelina recently welcomed baby Joel into their family in June of 2023.
